.75 mm Triple Ripple Diamond Drill - 6 pack

CRL Plated Diamond Flat-Tip Drills are to be used in hand-held DremelTM, Foredom or small precision drill presses. Diamond is plated on flexible music wire. Tripple-RippleTM Drills have twice the life and cutting rate of our Flat-Tip Drills. The Tripple-RippleTM Diamond Drill has three flutes to allow cuttings to flush away, and decrease frontal contact and drag. As the edges wear, fresh diamond in the flutes maintain the cutting action. NOTE: Always submerge in CRL Diamond Tool Coolant solution to prevent overheating and prolong long life.
